Abstract
In order to investigate the effect of drought stress (field capacity, 50 and 30% of field capacity) and foliar spraying with selenium and carbon quantum dots nanoparticles (zero and 2 mg L-1) on the growth and some physiological traits of rosemary; A factorial experiment was conducted in the form of completely randomized design in the research greenhouse of Azerbaijan Shahid Madani University during 2023. Irrigation at field capacity and 50% of field capacity with carbon quantum dot spray increased the aerial part dry weight, nitrogen, and soluble solids content in the plant. The highest malondialdehyde content was observed in the 30% field capacity in the condition without foliar spraying. The proline content was increased by 50 and 30% field capacity with the application of carbon quantum dot nanoparticles. Field capacity treatments, 50 and 30% of field capacity with carbon quantum dot foliar application increased the essential oil content. Rlative water content, carotenoid, chlorophyll b and phosphorus content increased in the field capacity and 50% field capacity treatment with both nanoparticles foliar application. Overall, the results showed that the use of carbon quantum dot nanoparticles had a positive effect on the growth and physiological traits of plants under drought stress
